Mogor Petroglyph (Pedra do Labirinto) is a labyrinth installation in Pontevedra, Galicia, Spain. The design is a classical 7circuit layout with 7 circuits, 8 walls, approximately 0.35 metres in diameter, built of rock carving. Documented age: ~3000-1500 BC (3000 - 1500 BC). Current condition: intact. Carved on a granite boulder overlooking Mogor beach in Galicia, this classical 7-circuit labyrinth belongs to the Atlantic Bronze Age petroglyph tradition spanning from Iberia to Scandinavia. Dating estimates range from 2000-750 BCE. Documentation sources: Saward 2003, Kern 2000. The labyrinth pattern occurs nowhere in nature; every documented instance traces back to a human hand. The labyrinth is one of several hundred sites of this type catalogued globally; each preserves the same unicursal walking-pattern with regional variation in scale, material, and date.
The labyrinth tradition spans at least 4,000 years of documented practice across northern Europe, the Mediterranean, the British Isles, North America, and the Indian subcontinent.
